Left Hand Kooima Ag Universal Knife Kit

HUGE SAVINGS
Save $80 per pair compared to OEM knives, buy direct, USA-made, field-tested, and proven without sacrificing performance or durability

The Kooima Ag universal knives fit the V-Max Claas® cutter drum. The set includes two Left Hand Knives (refer to notches on the knives) and four bolts. In conjunction with the shear bar, these knives are used to cut the harvested material. These high-quality knives are suitable for corn cutting. 

For the installation process of the knives, refer to the instruction manual included (or download below) or the installation video. 

Each of the knives are tungsten hard-faced and heat-treated to OEM specifications. A ground in cutting edge ensures a hardened blade all the way to the tip of the knife. Visually inspect the knives for wear, a ragged-looking cut material is a good indication. 

Kooima Ag has been producing replacement agricultural products for over 30 years. During those years, Kooima Ag has developed a proven track record of providing dependable and durable products at a cost-saving to our customers.

Upgrade your forage harvesting performance with the V-Max® Premium Universal Cutter Drum Knives. Designed for versatility and built to last, these high-quality knives are suitable for both corn and grass cutting. With a unique design and premium features, they deliver exceptional cutting efficiency while offering longer-lasting durability compared to standard knives.

Key Features:

• Unique Cutting Design: The knives are engineered with a specialized angle for cutting against the shear bar, allowing for easier cutting of forage. This design results in:
  • Less effort to cut, improving overall efficiency.
  • Cut-and-throw technique with the inside of the knife holding the forage, delivering better cut quality and faster throw for faster processing.
• High-Quality Construction: These knives are bolted securely to the cutter head drum with 2 bolts per knife for maximum stability and precision.
• Universal Fit: Designed to fit silage choppers with 20-24 knives on the cylinder, making them a perfect replacement.
• Durability and Maintenance:
  • Heat-treated for strength, ensuring resistance to wear and a sharp edge for longer.
  • Coated with Tungsten Carbide, which enhances durability and keeps the knives performing well under demanding conditions.
  • Sharpening Recommendations: Sharpen the knives 10-15 passes per hour during pickup work (e.g., cutting grass or cover crops). For corn silage and earlage, sharpen every 10-15 passes every two hours.
  • Shear bar adjustment is recommended to adjust your shear bar to the knives after sharpening to ensure consistent cutting performance.
• Easy Knife Replacement: Replace the knives when they become heavily chipped, cracked, or when the tungsten carbide coating is worn away. Additionally, replace clamps (K1318738 and K1319815) when replacing knives to ensure maximum holding power.
• Set Includes:
  • Two Left-Hand (LH) Knives.
  • Four bolts for easy installation.

Designed to meet factory specifications, these Universal Cutter Drum Knives offer a reliable, cost-effective solution for silage choppers working with both corn and grass.
